[PATCH] Fix tweak in similarity estimator.
There was a screwy math bug in the estimator that confused what -C1 meant and what -C9 meant, only in one of the early "cheap" check, which resulted in quite confusing behaviour. Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
